After the predictable outcry on social media from Swift fans, she tweeted: "I get asked questions. I answer them. Sue me. Also don't forget that words can be taken out of context when doing interviews.. still not apologizing for saying what everyone want to say.

She then wrote: "So excited for 2017. Taking a break from music and the spotlight.. I am not meant for this business and the media 👋🏼"
